Santa is real and does exactly what he is supposed to do. He delivers gifts to good children and coal to bad; and he does it all in one night. This sounds like an impossible task until you realize how mediocre most of us are. None of us is really good or evil, and neither are our kids. It is in the nature of every child to be selfish; it's a survival ...

They meet at sci-fi and cosplay conventions, dressed up as the Illuminati so they can discuss world conquest without worrying about being taken seriously.

Instead of fat, elves store energy as ethanol. Fats are the most dense form of food calories. Ethanol is a close second. From https://biology.stackexchange.com/questions/28511/what-is-the-most-condensed-form-of-stored-energy-used-in-biology Rather than pack on bulky fat, elves convert calories to ethanol and store it in their blood spaces and ...

The aliens are actually intelligently designed. The aliens and all life forms they are familiar with are designed by super beings. There are actually factions of super beings who design life forms for sport, artistic expression and other motives less comprehensible to lesser beings. Life forms are taken back, redesigned, new models rolled out and so on. ...

Slimes can't be harmed with weapons They don't have a solid form. Slash it with a sword, whack it with a hammer, poke it with a spear, and all you get is a wet thud. Slimes can't be harmed by fire They are so wet and gooey. If you throw a torch at them, it would go right out. Even a Grade A magical fireball won't do too much damage. You need a whole team ...

Before vascular land plants, there were weird fungal “trees.” People still do not really understand what exactly they were or what they ate. They were called prototaxites. from pinimg.com Wikpedia: Prototaxites Prototaxites is a genus of terrestrial fossil organisms dating from the Late Silurian until the Late Devonian periods, approximately 420 ...

Fat or adipose tissue carries out some very important functions, so if the elves are anything like humans—or like any sort of mammals—they need fat to survive. Long term energy storage is just one thing, but fat also produces hormones, contributes to thermoregulation and other good stuff. You know that friend of yours, the one that can eat ...

TL;DR: the people of your world could definitely have a concept of magic, even if it was a "legal" part of their world. This is because a) there are always things that people don't understand, and b) there's nothing that says the Scientific Method (or a system like it) is inevitable as a system of knowledge (or at least that is a huge assumption requiring ...

Your planet is a pulsar From Wikipedia, the acceleration caused by centrifugal force of a rotating object is $$\omega\times(\omega\times r).$$ Since the direction is known to be tangential to both the direction of rotation and the axis of rotation, and surface gravity acts in the opposite direction, we can just use the magnitude $\omega^2 r$. The ...

Santa's Elves are a distinct species, separate from other species of elves, characterised by their submissiveness, lack of imagination, endless patience, love of stable, predictable environments, and delight in performing repetitive, menial tasks. So, far from feeling oppressed by Santa, Santa's Elves thank Santa daily for providing them with the ...

There are a few ways to go about this... She's not the first Simply put she isn't the first English speaking person to be there, maybe of the few that came before her who spoke English one came into a position of power and the people just took up the language. It happens. Coincidence Simple enough, although in all honesty, it's a 1 in a who-knows-how-big ...

Imagine a planet interlaced with a giant crystalline network. This could either be a single set running straight through the planet, or an actual web of crystal throughout the entire thing. The source is natural - something about your universe encourages gigantic crystal formations under the conditions your planet formed. While in most places the crystals ...

"Kalgash is an alien world and it is not our intention to have you think that it is identical to Earth, even though we depict its people as speaking a language that you can understand, and using terms that are familiar to you. Those words should be understood as mere equivalents of alien terms-that is, a conventional set of equivalents of the same sort that ...

I can think of at least two reasons. The physics answer, If your disk is massive enough you get an interesting effect that causes it to behave more like a bowl than a disk even though it is flat, at least as far as gravity is concerned, the closer you get to the edge the steeper the surface feels. to a person on the surface it would feel like climbing a ...

The world would become progressively more alien as you moved across it. Unlike on Earth, where animals and humans can move across the entirety of the world given a few thousand/million/tens of millions of years, an infinite flat earth would always have somewhere that's far enough away that nothing from where you are has ever been there. This would probably ...

It seems that what you are after is a water clock. There's many designs, but the simplest is a water-filled jug in which floats a shallow bowl with a hole drilled into the bottom. Water trickles into the shallow bowl, until eventually it sinks. This provides a consistent and repeatable measure of time.

Cut off their tusks Fortunately, trolls have tusks. Cutting the end off of tusks takes a bit of work, but there is no blood involved, so it is suitable even for the squeamish. Note, horns are keratin over bone. Tusks are overgrown teeth. Troll tusks won't bleed.

There is a biological reason for gender roles being the way they are: Reproduction requires far more resources from a woman than from a man. A woman can only bear a child about once a year, takes severe discomfort and health risk from the process, and is only fertile for a few decades of her lifetime. A man, on the other hand, doesn't need to do more to ...

You're using Pratchett as your example so the answer is largely as he approached it. The world is big enough for everything it needs to contain. He was deliberately vague about distances and directions. The only accurate map is the map of Ankh-Morpork (and the basic railway map) because as he says in the introduction to The Streets of Ankh-Morpork: I've ...

Strange thing? We already stack the Earth. Not quite as grandiosely (is that really a word??) as you're asking for, but when you think about it modern cities, especially those with skyscrapers, are attempts to do exactly what you're doing. So rather than getting the world engaged in a megaproject to build a series of 100km high shells, instead get the world ...

Genocide The surprising fact that nobody has covered in detail as of yet is the elephant in the room - that of genociding the Blue faction. We have heard of many genocides, but most of them were unsuccessful (Yugoslavian genocide, Rwandan genocide, Ottoman-Armenian genocide and the Holocaust, to name a few). We might therefore be tempted to think that ...

Santa could have a perception filter. Adults think they buy gifts, and see the nightmare after Christmas (the credit card bills) as appropriate. They don't see the sleigh on top of the roof, and ignore any reindeer poop on their cars as just evidence of a very ill pigeon. As kids get older, the perception filter starts to kick in retroactively. After all,...

They were quite cunningly hidden, but I finally discovered the hidden Illuminati ploy to meet at the regular European Tax and Regulatory Compliance Group for the Cucumber Growers Association meetings, held once a month in a regular hotel in various small post-industrial towns in Western Europe. They will use code words like Cornering the Cucumber Market for ...

Make your world finite but spatially bounded. This means anyone walking towards where the edge would be will find themselves inexplicably turned around, even though they were still walking in the same direction and to their own minds they didn't turn around. They will arrive back at the place where they started. The Arthur C Clarke short story "Wall of ...

Elves have thicker skin. Literally. One of the purposes of fat in the body is kinetic: it serves as a cushion to absorb and distribute the force of impacts - not just in the sense of punches or falling rocks, but also things like the ground impacting your foot as you walk around on it. Since your elves don't have fat, it follows that some other part of the ...

It seems to me that your angels wouldn’t be invincible, impossible-to-defeat warriors with the parameters you’ve set. Like other answers have said, since they have to land eventually, they will be vulnerable to the other, larger races in your world. While they would be excellent raiders and quite powerful warriors (a wine skin filled with flammable oil and ...

Tide chart. The moon is concealed. But it is still there. The moon pulls on the sea and causes tides.

Because they convert any excess energy directly into mana. As stated they are powerful mages, and as such are deeply linked with magic, and it's fuel, the omnipresent Mana. Thus they - or at least the more magier ones - eat A LOT of calories. It's just converted to astral energy which surrounds them on another plane. Thus they do get fat - just not in this ...

Slimes are very big. The little puddle on the floor is to the body of the slime as a mushroom is to the mycelium below. The mushroom is the size of your finger. The mycelium is the size of a car. Most of a slime's vast biomass (and even vaster water mass) is kept safe from dessication in the interstices and cracks of the substrate. Only a tiny bit ...

This question cannot be answered as we simply do not know. We have a sample set of 1 - us. Based on that sample set the answer is 4.5 billion years, however we have no idea what factors would make that a much shorter or much longer time.
